PIPE AND FLUE CONNECTION.

IPECIFICATION forming part of Letters Patent No. 365,783, dated July 5, 1887.

Application filed NOVQIllbiI 13, 1886. Serial No. 219,728. (No model.)

To all whom it may concern:

Be it known that l', VINcENzo BONZAGNI, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Stove and other Pipe and Flue Connections, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a section through a chimneyflue with a thimble and stove-pipe collar applied thereto in accordance with my invention; Fig. 2, a perspective view of a thimble to be permanently located in the passage of the chimney-flue; Fig. 3, a perspective View of a plate and stove-pipe collar, preferably formed integral; Fig. 4, aplate with its ventilating device. Fig. 5 shows the application of my in-' vention to gas or lamp burners, &c.; Fig. 6, an elevation of a plate constructed in accordance with this invention, and tobe applied to the thimble shown in Fig. 2.

To avoid the annoyance and delay incident to the ordinary means of fitting stove-pipes to chimney-fines is the chief purpose of this invention, which consists'in two principal features associated together-to wit, a thimble of fixed and unvarying size to be permanently located in each chimney-flue and a series of stove or furnace pipe collars or plates having openings ofdifferent diameters-73. 6.,13116 opening in one collar or plate being of a diameter difi'erent from the opening in another plate or collar-so that pipes of different diameters may be accommodated by using different plates or collars, every one of the plates outside being of the same size and exactly corresponding to that of the seat or place intended forits reception within the thimble in the flue, by which construction and arrangement, when a person wishes to put up a stove, it is only necessary to obtain at the shop one of the collars or plates having the pipe-opening therein corresponding in diameter to that of the pipe to be fitted, and after having placed it over the pipe to enter the plate within the thimblein the flue for its reception, the outside of any plate for a small pipe collar or opening being of the exact size as the outside of a plate having a larger pipe collar or opening, and adapted to snugly fit into and be secured, byscrews or otherwise,

to the thimble in a convenient and expeditious manner.

Y My invention also consists in a pipe of smaller diameter connected with a cap located over a lamp or gas burner, in combination with and leading to a plate having an opening to receive said pipe, and secured within the thimble or chimney-flue, whereby the smoke and foul air and gases are carried out of the apartment.

In the said drawings, A represents a section of a chimney-flue, within the passage act which, leading to an apartment, (not shown,) is located a metallic or soapstone thimble or casing, B, having a flange, 1), extending around its outer edge, which incloses a recessed seat, 0, for a rectangular plate, 0, of corresponding size, which fits snugly therein, preferably flush with the outer surface of the flange b. This thimbleis provided with a large central hole, d, of a diameter always sufficient to receive the largest size, as well as the smallest size, of stove or furnace pipe employed, said central hole being'of a size sufficient also to receive a tubular section, 0, of any size, when one is cur ployed, at the back of the plate 0, for the purpose of providing a more extended bearing for the pipe where it enters the hole 0 of the thimble B. The front of the plate C may be provided or not with a collar, h,- but as it im parts a finished appearance to the plate, and also materially strengthens the union thereof with the tubular section 0, I prefer to employ it, and it may be made separate from or integral with the plate 0. Near the corners of the plate, and also at corresponding points in the recessed seat 0, countersunk holest' are formed for the passage ofscrews, by which the plate may be held in place.

Were the thimbles used in chimney-fines all of the same size-4'. 0., each havinga recessed seat of the same unvarying size to receive any number of plates 0 of the same unvarying size outside as the seat of each thimble, so as to snugly fit therein or thereon, and with differcut-sized openings for differentsized pipes, and were each thimble also provided with a central opening, (1, large enough to accommodate a stove or furnace pipe of any size--it would be an extremely simple operation to fit any pipe into a chimiieyfiue, for the reason that were the pipe five inches in diameter a plate therefor having an opening of five inches could be therein.

obtainable at the stove-shop, which would be sure to fit the t-himble 0. So, likewise, if the pipe to be fitted were five and one-half inches or six inches in diameter, a plate having an opening of either five and one-half inches or six inches could be purchased and a snug and perfeet connection made with great facility. The flange b at the outer edge of the front of the thinible may be dispensed with and the plate bear on the outer surface of the thimble, care being taken, however, that the screw-holes t in thethimble and thosei in the plates be directly in line or register with each other. Should the stove or other pipe be removed from the chimney-flue, a ventilator, D, similar to that shown in Fig. 4, may be placed within the seat 0 pf the thimble, the size of the outside of the ventilator-plate being of the same size as the outer edge of the seat, so as to exactly fit I prefer to cast the plate 0, its tubular section 6, and its collar h in one and the same piece, as thereby they can all be handled and fitted in position at one operation. I may, however, cast the tubular section 0 and plate 0 together, and apply the collar as a separate piece to the pipe.

To rid an apartment of the smoke and disagreeable and impure odors proceeding from lamp and gas burners, I resort to the following-described arrangement: Immediately over the burner is is located a cap, G, which has an opening in its top, and is connected with a small pipe, I, supported by a bracket, F, from the side of the room. The opposite end of the pipe I enters a hole, on, of corresponding size formed in a plate, 0, screwed within the seat 0 of the thimble, as before described, this pipe, besides relieving the room of the smoke and foul V odors and gases, also conducting away any objectionable heated air which may be generated in the room from the gas or oil when burnmg.

I am aware that a stove-pipe thimble consisting of an outer case substantially square in crosssection and fitting into the aperture from an apartment into the flue, and a cubiform case fitting snugly within said outer case and having in its side walls openings for stovepipes of different sizes, is old, such a construc-' tion being illustrated in United States Patent No. 34,743, to W. W. Davis, dated March 25, 1862; and hence I disclaim such earlier device.

I claim- 1. The herein-described removable chimneyflue thimble having a portion adapted to extend into a flue and an exposed face, which latter has an aperture, d, therein, in combination with a perforated plate, 0, removably attached to the exposed face of said thimble, the perforation in plate 0 being smaller than aperture d, substantially asset forth.

2. The herein-described stove-pipe thimble B, it having formed in its outer face an aperture, d, and being provided with a flange, I), surrounding said plate, whereby there is formed a recess, a, in combination with a perforated plate, 0, adapted to be seated in said recess, substantially as set forth.

3. The plate 0, a tubular section, 6, extending through said plate, and a strengtheningfiange, h, between said plate and tubular section, said flange being cast integrally with theplate and tube-section, substantially as set forth.

' \Vitness my hand this 19th day of November, 1886.
